Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a clamping auxiliary mechanism for automotive stamping dies. Background Technology

[0002] With the gradual improvement of society's technological level, automobile manufacturing technology has also achieved unprecedented development. In the process of automobile production and manufacturing molds, stamping dies are often used to forge automobile parts. When most existing molds are used on stamping presses, certain fixing fixtures are often used to fix the molds.

[0003] A search revealed Chinese Patent Publication No. CN215144033U, which discloses a clamping fixture for stamping dies in automotive parts processing. The fixture includes a fixture body with a clamping mechanism fitted onto its surface. This clamping mechanism includes a rotating component with rotating blocks evenly fixedly connected to its surface. One end of each sliding rod is fixedly connected to a clamping rod, and one side of each clamping rod extends through the fixture body into its interior. An anti-collision mechanism is provided inside the clamping rod. This technology allows users to quickly clamp the die simply by pulling a pull ring and rotating the rotating component. The anti-collision mechanism allows users to quickly move the threaded rod outwards towards the clamping rod by continuously turning the rotating block, rapidly bringing it into contact with the clamped die, thus increasing the clamping effect for some irregularly shaped dies.

[0004] Existing clamping auxiliary mechanisms for stamping dies cannot effectively clamp stamping dies of various shapes and sizes. Furthermore, automotive stamping dies have many shapes and cannot be clamped accurately and reliably. Direct clamping can easily damage the dies. Therefore, a clamping auxiliary mechanism for automotive stamping dies is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model embodiment provides a clamping auxiliary mechanism for automotive stamping dies, such as... Figure 1-6 As shown, the device includes a clamping shell 1, a tightening component 2 disposed inside the clamping shell 1, a guide component 3 fixedly connected to the inside of the clamping shell 1, a pressing disc 4 rotatably connected to the surface of the guide component 3, the pressing disc 4 being connected to the tightening component 2, a clamping component 5 disposed inside the guide component 3, the pressing disc 4 being annular in shape, an array of arc-shaped grooves 41 disposed on the surface of the pressing disc 4, and teeth disposed on the inner circumferential surface of the pressing disc 4, the tightening component 2 including a tightening motor 21 and a tightening gear 22, the tightening gear 22 meshing with the teeth on the inner circumferential surface of the pressing disc 4, and the pressing disc 4 being able to drive the clamping component 5 to move by rotating through the arc-shaped grooves 41 on its surface.

[0028] The clamping assembly 5 is provided with a clamping arm 6 at its upper end. The clamping assembly 5 includes a slider 51, which is slidably connected to the guide strip of the second guide plate 32. A sliding post 52 is fixedly connected to the upper surface of the slider 51. The sliding post 52 passes through the inner side of the arc-shaped slide groove 41. A straightening block 53 is provided at the upper end of the sliding post 52. The straightening block 53 is slidably connected to the inner wall of the slide groove of the first guide plate 31. A linkage sleeve 54 is fixedly connected to the upper end of the straightening block 53. A protruding plate is provided at the center of the inner side of the linkage sleeve 54. The linkage sleeve 54 is slidably connected to the clamping arm 6. The clamping assembly 5 can move along the guide assembly 3 after being squeezed and pushed.

[0029] The guide assembly 3 includes a first guide disk 31, which is circular in shape and has a groove on its surface. A second guide disk 32 is provided on the lower surface of the first guide disk 31. The center of the second guide disk 32 is a cylinder, and guide strips are arranged in an array on the surface of the cylinder. The guide assembly 3 can control the sliding direction of the clamping assembly 5 by using the first guide disk 31 and the second guide disk 32, so that the clamping assembly 5 moves more stably after being squeezed.

[0030] The clamping arm 6 includes a clamping block 61. The end of the clamping block 61 near the center of the clamping shell 1 is provided with anti-slip teeth. Two clamping springs 62 are provided on the inner side of the clamping block 61. The two clamping springs 62 are respectively provided on both sides of the protrusion of the linkage sleeve 54. An auxiliary clamping plate 63 is connected to the upper end of the clamping block 61 by screws. The clamping arm 6 initially clamps the stamping die through the clamping block 61. By setting the clamping springs 62, the clamping arm 6 can generate a rebound when clamping. Since the clamping arm 6 closes and clamps at the same time, the clamping springs 62 can also prevent damage to the stamping die.

[0031] The clamping assembly 5 is provided with a compensation mechanism 7. The compensation mechanism 7 includes a positioning shell 71, which is fixedly connected to the linkage sleeve 54. A compensation ratchet 72 is provided inside the positioning shell 71. One end of the compensation ratchet 72 is a transverse cylinder connected to the clamping block 61, and the other end is a longitudinal cylinder connected to the pushing mechanism 8. An anti-rebound mechanism 73 is provided inside the positioning shell 71. The anti-rebound mechanism 73 consists of an independent ratchet 731 and a return spring 732, which is used to prevent the compensation ratchet 72 from moving in the opposite direction. After the compensation ratchet 72 is pushed, the compensation mechanism 7 can push the clamping arm 6 to move inside the linkage sleeve 54, so that the clamping arm 6 is pushed a second time, so that the clamping arm 6 can better fit and clamp with the stamping die. The anti-rebound mechanism 73 is provided to prevent the clamping arm 6 from loosening after clamping.

[0032] The compensation mechanism 7 is connected to the clamping arm 6. A propulsion mechanism 8 is provided inside the clamping shell 1. The propulsion mechanism 8 includes a propulsion motor 81. A propulsion gear 82 is fixedly connected to the output end of the propulsion motor 81. A rotary ring 83 meshes with the outer surface of the propulsion gear 82. The outer surface of the rotary ring 83 is provided with teeth. The rotary ring 83 is rotatably connected to the clamping shell 1. A compression spring 84 is provided inside the rotary ring 83. The compression spring 84 slides and compresses against the longitudinal cylinder of the compensation ratchet 72. The propulsion mechanism 8 can push the compensation ratchet 72. The compression spring 84 allows the compensation ratchet 72 to be pushed by the spring, resulting in a flexible push of the compensation ratchet 72. When the compensation ratchet 72 is obstructed during the push, the compression spring 84 deforms and slides over the longitudinal cylinder of the compensation ratchet 72.

[0033] Working principle: In use, the mold to be clamped is first placed on the surface of the clamping shell 1. The tightening motor 21 is started to drive the tightening gear 22 to rotate, which in turn drives the extrusion plate 4 to rotate. The extrusion plate 4 rotates and pushes the slider 51, causing the clamping assembly 5 to slide towards the center inside the guide assembly 3. This causes the clamping block 61 to move towards the center and clamp the mold. The propulsion motor 81 is started to drive the propulsion gear 82 to rotate, which in turn drives the rotary ring 83 to rotate. This causes the extrusion spring 84 to push the compensating ratchet 72, which in turn pushes the clamping block 61 to move towards the center, making the stamping mold clamped more tightly. After being pushed, the compensating ratchet 72 is blocked by the anti-rebound mechanism 73, making the clamping arm 6 clamp more tightly. The compensating mechanism 74, which is not pushed by the extrusion spring 84, will bend and slide past to avoid it. This allows each clamping arm 6 to extend to a different length and fit against the stamping mold, so that stamping molds of different shapes and specifications can be firmly clamped.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
